Fabrication and characterization of C/PTFE cathode for hydrogen peroxide synthesis through alkaline fuel cell reactor

A fabricating method of C-polytetraflouroethylene cathode, C/PTFE, for hydrogen peroxide synthesis through alkaline fuel cell reactor was studied, and the primary influential factors of fabrication were investigated. The performances of cathodes at different fabricating conditions were evaluated by the voltage-current curve, concentration curve of H₂O₂ and AC impendence diagram. The results showed that cathode performances were much affected by the pressure, carbon content and PTFE content in the flattening layer. When the pressure was 10.0 MPa, carbon content 0.2 g, and PTFE content 50%, the maximum current and high output of H₂O₂ were produced, and the concentration of H₂O₂ reached 56 mmol/L after 2.5 h.
